WUQ FNIRSI-2C23T 3-in-1 Oscilloscope Multimeter Signal Generator

All-in-One Test Instrument

The WUQ FNIRSI-2C23T combines a dual-channel oscilloscope, a digital multimeter and a DDS signal generator in one handheld unit. It targets engineers, technicians, educators and hobbyists who need portable measurement capability across multiple domains without carrying separate devices. The integrated design reduces bench clutter and simplifies field work.

Replaces Separate Bench Tools

This instrument consolidates three distinct pieces of test equipment into a single package. The jump is worth it when workspace is limited, when moving between sites, or when rapid switching between waveform capture, precision voltage or current reading, and stimulus generation is required. It eliminates the need to synchronize separate instruments during mixed-signal debugging.

Battery-Powered Handheld Platform

The unit runs on a built-in 3000 mAh rechargeable cell charged via USB Type-C at 5 V 1 A, providing roughly six hours of standby operation. A 2.8 inch 320 by 240 LCD presents waveforms and readings, while an FPGA plus MCU plus ADC architecture handles acquisition and protection up to 400 V. The handheld form factor frees bench space and enables on-site diagnostics without mains power.
